Automotive Products for Safety

Murata Automotive Products for Safety feature sensing technology that provides precision control by electronics, essential for the safety systems of vehicles. These Safety Products offer the high reliability that is provided by ceramics, which can endure severe operating conditions. Murata's electronic components, including various sensors, support a pleasant driving experience with excellent performance by the latest technology. 

Automotive Circuit Protection / Thermistors

Murata Electronics Automotive Circuit Protection and Thermistors include a wide lineup of characteristics for various electronic devices, including smartphones and wearable terminals, and automobile/automotive devices. Heat is generated by applied voltage and current, and the resistance changes along with the temperature. Murata thermistors function as a heating element and thermo-sensitive device and play an active role in various applications, such as temperature sensors, circuit protection, and temperature compensation.

POSISTOR® PTC Thermistors

Murata POSISTOR® Positive Temperature Coefficient (PTC) Thermistors are ideal for circuit protection in a variety of applications, such as temperature sensor and temperature compensation. These devices are also suitable for current control in common household appliances, humidifiers, dryers of all kinds, refrigerators, freezers, and air conditioners. In a conventional NTC thermistor, the resistance decreases when the temperature increases, but for the Murata PTC thermistors, the resistance rises sharply when their temperature exceeds a specific temperature.

Automotive Products

Murata Electronics supports the automotive market by supplying precise sensing technologies and high-reliability electronic components that are essential to the smooth operation of a vehicle. The evolution of automotive technology has been facilitated by electronic components that monitor the vehicle inside and out and exchange information among the components. Whether an engineer seeks timing devices, circuit protection, noise suppression, or inductors and capacitors, Murata provides a wide selection of automotive-grade and AEC-Q200-qualified products.  Murata's technology and know-how help contribute to developing a "ubiquitous network society," preserving the global environment and creating a future with safer and more comfortable automobiles.

PRF PTC Thermistors

Murata Electronics PRF Series PTC Thermistors offer a fast response time, 470Ω to 10kΩ resistance range, and 2mm x 1.25mm maximum dimensions. PRF thermistors accurately detect overheating in multiple areas using a very simple circuit through sharp changes in resistance. Using sharp changes in electrical resistance also translates into outstanding noise resistance. Murata PRF Series PTC Thermistors are ideal for mobile phones, power supplies, LED bulbs, and automotive applications.

Automotive Products for Powertrain

Murata Automotive Products for Powertrain are ideal for engines, electronic power steering, and xEV powertrains. These Powertrain Products offer the high reliability that is provided by ceramics, which can endure severe operating conditions. Murata's electronic components, including various sensors, support a pleasant driving experience with excellent performance by the latest technology. 

Thermistors

Murata Thermistors use semi-conductive ceramic and electrode printing techniques to form a temperature sensor with negative temperature characteristics, meaning resistant values decrease as ambient temperatures rise. Murata Thermistors are used widely for temperature detection devices, inrush current protection, and temperature compensation in electronics such as mobile devices, secondary batteries, and automobiles. Murata offers a variety of thermistor products to meet the demands of many applications.

AI Server Application Solutions

Murata Electronics provides a wide range of products suitable for AI environments and applications. Due to demanding AI requirements, engineers must address challenges like heat management, power efficiency, and signal integrity to keep pace with the increasing complexity of AI workloads. These advanced, reliable components from Murata help meet these challenges head-on. Designed to ensure optimal performance, efficiency, and reliability in AI server infrastructure, these products enable engineers to create systems that can scale with future advancements in AI.
